A Print Devil can be any age


Was 9 year old kid who knew nothin’ about printing.
Walked down a dirt road, stopped at print shop,
sat on doorstep – ‘n watched.
‘Bout ‘hour went by — i asked this guy wearin’ a
‘sorta’ funny lookin’ thing on his head with no top,
had a green visor hangin’ over his eyes. “like those card
dealers in `Vegas wear.”


Need help sweepin’ floors or somthin’?
A
nswer comes back.
Maybe.
“ `mon in. Grab a sody water – ice cooler over there.
We’ll talk about it.”

Another worker saw me . . . walked over . . .
asked — “don’t ua’ work for Mayor Phil at milk barn?”
Yup. just got done sweepin’ alleys (area behind cows when milked).

Guy with “funny hat” asked sum questions.

Hows ur’ spelling?
We do 10 new words a day.

Get ‘em all correct?
 Nope.

Any hunderds?
Yup. One, maybe two.

Someone tole’ me ua’ wash them there glass bottles on
that steam spittin’ spinning brush?
Yup. ‘bout 20 cases (240 bottles) each day   [Quart - Pint - 1/2 Pint]

Why ua’ wanna’ work here?
Washin’ bottles, feedin’ cows and collecting eggs - 1 year - tired of that.
Had fun riding Peanuts [pony] rounding up cows - 5 p.m. milking.
dog Shep came with every day.
Cows saw us – started moving to barn.

Does Farmer Phil know ur’ tired of doin’ this?
Yup. He tole’ me to stop by here.

OK. ‘comon. I’ll show ua’ where the broom is –
OK. ‘comon. and don’t get near those printin’ machines.
OK. ‘comon. They sometimes get hungry when ‘ua walk by ‘em.
OK. ‘comon.
Sorta’ reach out n’ grab a shirt sleeve. They ain’t fussy.
OK. ‘comon. Like to chew fingers off!

•    •    •    • and life went on . . . at the print shop . . . ‘till we moved
                                              
down Menominee river, 60 miles, Marinette, Wi., where
                                               dad obtained new employ.

Pony I rode, Peanuts, herded cows to barn for milking time.

Shedding “winter coat.”


Printers don’t talk everyday words like normal 9 year olds speak

No S-I-R   R E E E E E E E E . . .
I talked farm
words like hay bales, corn cobs, oats, glass milk bottles, halters, reins, tugs, double tree, hitch pin, clevis, horse shoes, ice corks, milk pails, saddle, cinch ring, milk crates along with a spinning brush that spit [200°±] steam inside of bottle.

Printers used words like picas, points, didots, cicero, line rule, leads, coppers, brasses, mutt, nut & thin spaces, slugs, hell box, type notch,  reglets, quoins, leaders, galleys, gutters, turtles, quoin key, space bands, vice jaws, hot metal, matrices, distributor box, metal pot, 1st elevator, 2nd elevator, clutch leathers, quadders, distributor box, mixers and on and on.

I was telling mother about all these words and mentioned the word “hell box” which caused her, while pealing potatoes, to turn around and point a knife at me and exclaim “their ain’t no such thing as a hell box!” You better get back to milk bottles, oats and that pony.

 Next day my dad stopped at this print shop and did in fact find out there was a hell box.”

 [U never threw a broken part or bent matrix away. Those things went into the hell box. Never know when u’ might need a bent or broken part to get a print press or hot metal linecasting machine or press running again.]

For a kid who knew “gee” and “haa” to get horses to turn left or right and how horse apples got from stalls to the pile in the farm yard, this Print Devil thing was a whole new world!

. . . from Print Devil to ? ? ?

First exposure to graphics and printing was hand setting newspaper headlines for a
North Eastern Wisconsin Newspaper. It was different than sweepin’.
 
This time I got to assemble “type characters” onto a galley that became column heading in the newspaper. The next day I got to distribute those letters back into the wood box (california job case) so they could be used another time. I’m still called a "printer's devil", just doing different stuff.

 

What are Leads & Slugs?
All Foundry Type had a NICK on the front edge of each character.
After setting the first line and before inserting any lead (space between lines) the compositor would make a quick check to see that all characters in the line were set correctly. If one character showed up with no nick - it’s time to turn the character around so the nick shows before inserting a “lead” space  strip of lead material – thickness of 1, 2, 3 points thick which are precut in many different lengths.
Also used for spacing between lines of type are “slugs” – that are cast in long strips then precut to lengths desired for line spacing. Thickness = 6, 12, 18 & 24 pt. thick.

‘bout this time, 1948, let’s see . . . I delivered milk bottles from a horse drawn cart to customers door steps, raised “squab” for sale, sold fresh eggs from my two chickens, learned how to swim in Menominee River (Michigan/Wisconsin border), delivered 98 papers to homes - tossin’ ‘em from my bicycle, made ice cream at a dairy, worked as helper in a Mobil Gas- 2 bay - Station, learned a lot of mechanical stuff about cars, worked at Radio WMAM, Marinette, wi., helped with installation of WMBV -TV, ch. 11, Marinette, Wi. (now in Green Bay, next to Lambeau Field. FOX broadcasting owns station.) and all of a sudden it was 1955. Out the High School door in June and onto one of those iron boats that picked up iron ore in Duluth, Mn. and hauled it to Inland Steel, Indiana. Then back to Duluth for another load. July, Aug. & Sept. E’nuf of that. Back to the Mobil station. . . then into U. S. Navy – Nov. of ‘55. Some of my Navy days consisted of building another TV station on Adak, Alaska, operating a garbage barge for U.S. Navy, converting a Navy Picket boat into a sport fishing boat for Navy dependents in San Diego.

Winnecone Wi. newspaper/print shop, after U.S. Navy, was next stop . . .
other activities will be filled in — later. . . . much later.

‘Bout 1960 I got back to basics of printing at Milwaukee Vocational School.
Linotypes, Intertypes, Ludlows and more.

 

What’s a point?
What’s set width?
What’s % of ink color reduction?

 

United States uses a measurement system based on inches, feet, yards etc.
For typesetting, 72 points = 1 inch. 1 point = .01387 thousandths of 1 inch
rounded up to .014 thousandths of 1 inch.

Aril & Arial Narrow typeface used in examples below.

 6 pt. type = ..084 thousandths of an inch.

 

 

 

 

 

 

 

 

 

Sample left is 6 pt. type = .084 thousandths of an inch. It’s used in advertisements, usually at the bottom, items that advertisers are required by law to reveal/publish BUT don’t want you to read nor understand. Also used in legal forms requiring signatures and Credit Card Co. rules about the use/payments etc. that You agree to before using the service.
Technology for type composition using computers, 1973 era. allowed composition of text to “squeeze” the set width of characters - by selecting a “Narrow” typeface.

Around 2009, technology offered commands to auto-squeeze
any type face to desired width. Some states have a minimum point size for classified and legal documents type, however, no state has established a minimum set width that this author is aware of.

“squeeze” the set width of characters.
to make sure –
     /\    /\   /\   /\     /\    /\
you can’t read certain type – 100 % black ink – 60 % = 40 % for black.
If still readable – reduce it another 10% or 20%.


 

 

 

 

 

 

 

 

 

 

 

 

Below line = 7 pt. Arial typeface.

Composing (composition) Stick

Above is Capital Letter “B” Foundry type — See “NICK” on character.

Composition “stick” was designed for persons – “right handers” - therefore held composing stick in left hand. Usually held in left hand allowing right hand to pick type characters from the type drawer (down page) one character at a time. I’ve seen a good typesetter pick two or three characters at a time. Note: in between the word “Art and” is a space, then after the word “and” a word space is being held with the left thumb. Possibly this line will get blank spaces inserted to fill out to upper edge (above thumb) top end of composing stick. Typesetter will then choose a “lead” or “slug” of desired thickness and length and inserts next to the type and spaces. The next line will start next to the adjustable measure guide. (under the Cap letter “A”

Adjustable line length clamp is adjustable to desired length of line required.
Lifting a lever allows movement to longer measure, then re clamping lever down again.
 

 

Adjustable Composing Stick

This shows how adjustable guide is operated plus “hand stick” is held.
Note spaces between each word plus a “lead” between the bottom of top line and second
line (typesetter’s thumb). This process continues until “stick” is full. Type will be
transferred onto metal galley tray – typesetter will continue with more typesetting
from type case below. With completion of typesetting accomplished a proof of type
in galley will be created on proof press. (down page) Proof read for errors. Correction
performed right on galley and then type can be placed into square iron frame known
as a “chase” – type will be held in “chase” by block of wood “furniture” then “quoins”
inserted between the furniture and “chase” frame - “keys” will be expanded with
“quoin key” –  then chase placed onto platen press.

I’ve written and printed left handed since 193?. Been intimidated by – countless teachers who wanted to tie my left hand behind my back – and concentrate using my right hand – however when I started typesetting and there were no composing sticks [below] for left handed typesetting persons . . . it took but a mere two minutes to retrain my thinking about holding the “stick” in left hand and doin’ type pickin’ with right hand. Wasn’t gonna’ walk away from this learning experience. Nooo Si r r r Reee.
To this day I use either hand to complete tasks. Whichever is most handy.

Composition stick held in left hand required
right hand to pick characters from “job case”. [see white drawer below]

Each letter in the headline was an individual character molded from lead, more commonly known as foundry type. The process was called "hand stickin’ type." You set the characters of foundry type, side by side, upside down for the headline in a long metal tray referred to as a stick or type galley. (metal tray made of heavy steel with 1//4” sides on 3 sides – leaving the end of the tray open so type could be slid off of galley tray into a form. If the line of characters were too long for the space intended in the newspaper you would distribute those characters back into the type drawer and go to the next smaller size type face and reset the line again.

After a couple days of this, you got to know which type would fit into a given space.

The makeup person would determine the length of line and typeface that should fit. He would place a white chalk mark on the metal galley where the line should end.

The foundry type (above) came in many different sizes – from 5 pt. (like classifieds ads in newspapers) to 148 pt (like 2” high headlines in newspapers.)

The average size of text in news stories appearing in a newspaper is 8 pt type – 8 pt type.

The next lesson to learn is were all these characters were stored in the below drawer. Capital letters were easy BUT lower case, ligatures, punctuation were a total mess.
(see California Job Case below:)

I never got a real explanation on why they were all mixed up.
I did find out that the “e”, being the most used vowel, required a larger space for storage.

California Job Case      Type drawer(below) has 89 separate spaces for storage of characters
                                           Some spaces for lower case letters were larger — used more often in
                                           composition.
                                           Larger type sizes were divided into two drawers — with larger spaces.


When selecting a drawer of type, you always pulled the drawer directly below your selected type drawer 1/2 way out. Then if you had to get to numbers in the top row of your type drawer and pulled the drawer out too far – it would fall to the next drawer – not all the way to the floor,  creating one “hell  of a mess” – which was called “pied type.” Those who pied a drawer got the [mandatory] opportunity to clean (redistribute) the characters to the correct square storage area within the drawer
On Their OWN Time! [after school hours]

Type (fonts) characters were stored in large drawers called California Job cases. These drawers were 32" wide x 17" deep x 1.5" high which were divided into many different size spaces. Larger spaces for vowels and spacing materials. Smaller spaces for consonants, numbers, ligatures, punctuation and special characters. Most drawers of type had 89 separate spaces. The larger type was divided between 2 drawers. Caps in one drawer and lower case, the other. You would stick all caps required for the headline, close that drawer and select all lower-case to complete the headline. As many as 60 drawers were in a type cabinet.

Above the 2 columns of type drawers are vertical stacks of 1 and 2 pt. leads use as space between lines of hand set type. Many different lengths - from 6 to 24 picas. Above them, the angle storage squares held different brass spaces used for spacing between characters within the words - to justify the lines of type in a composing stick when required



This print devil had to stand on a stack of three CoCa-Cola cases to reach the top 4 drawers.
(That's when a short bottle of Coke cost 5¢.

The cooler for the Coke was a large square tin box w/ folding covers.
¼ chunk of ice was delivered, via horse drawn wagon,
every other day for 10¢.
(Print Devil got elected to empty pail of water from cooler every 2 days)















“Hand set” type is composed up-side-down on a type galley. (picture right)

Place the galley onto a proof press, roll  ink on face of characters with brayer (roller), place sheet of paper on type then move (large roller) impression roller across paper.

Proof press (left) was invented around 1810

Type shops in the country  used them until photo composition
arrived in the 1960’s

Present day hot metal type shops still use them

(believe it or not– hot metal typesetting is alive and well)

The trade is taught at


Linotype University
located in Denmark, Ia.

Cold Beer Here!
Another print devil daily duties was take two empty pails to the corner pub,
(Ye' Olde’ Oak Tavern on square – Marinette, WI.) and have them filled with beer.
A ritual performed each day when the newspaper was "put to bed." (Placed onto the press)


All comp room personnel would locate their mug, gather around this huge flat stone table (below)
where pages were "made up" (imposed/assembled) and partake in “swilling” of beer.

The barkeep traded 2 pails of beer for 2 FREE newspapers —
compliments of the newspaper publisher.

Tramp Printer — Ever hear of them?
How about Drifters?

Read on to learn more

Tramp Printers would traverse the country  from East to West Coast and North to South, depending on where the best weather was. One could show up at any newspaper or commercial type shop and request work. It was difficult to find good people who could hand stick type and be a good speller. They were never turned away. Always showed up with no money. Most of the shops had a Chapel Chairman. Like a Union steward today. The worker would converse with the Chair who in turn went to the owner or publisher and cut a deal for the Drifter to work. If the pub/owner refused, then another permanent worker would take a day off and have this worker take his place. The problem with a permanent worker taking a day off, he would visit the other shops in the area and possibly take employ at a different location. Then when the Tramp left town – his former employer would be short of GOOD help. People who could hand stick type were always in demand. Owners would hire a housewife before a male. Women had smaller fingers and could hand stick type faster than most males. However in those days the rules were different for women. If they had children, they stayed at home tending to them.
The tramp drifter wouldn’t stay for long. Maybe a week or so.
The local saloon always had food for them and a place to sleep. The tramp drifters never left town without settling their tabs at the local saloon.
They might be back in 6 months. And be graciously welcomed by the Saloon keepers with
all sleepin’, eatin’, drinkin’ on the house!





Long before Gutenberg's invention entered the scene, Germany was already a center of European book culture.   Books were hand-made by monks in monasteries, who toiled for weeks over a single manuscript and were primarily responsible for copying religious documents.   Illuminated with gold and beautifully illustrated with colorful drawings and designs, these books remain some of the most important medieval cultural artifacts in Germany.

Forward to 1955 —

This print devil joined the U.S. Navy. Started as a Seaman Apprentice (same as printers devil — do the crappy work) and was whisked away to Adak, Alaska to operate a TV station for the entertainment of troops. (the devil worked at WLUK-TV 11 Marinette, WI. while in high school) Air Force, Marines and Navy plus some dependents were stationed there.. Television, small 12" screens that produce black/white pictures on a glass tube along with speakers that blurt out sound and have more snow on the screen than picture.

Adak is so far out of touch with the real world that map makers created a westward jog in the International Date Line so the last island on the Aleutian Chain, Attu, would be included within the continent of North America. Adak Island is 5 or 6 from the end of the chain.

Wow...

Fairchild Teletypesetter Perforator

This Teletypesetter Perforator Operator’s Training Reference Manual was published in the middle to late 1950’s by Fairchild Graphic Equipment, a division of Fairchild Camera & Instrument Corp., Fairchild Drive, Plainview, LI., New York.

The factory was located about 30 miles from Mid-town Manhattan – on Long Island, NY, in the middle of a potato field.

In 1962 I worked for Fairchild Graphic as a TTS equipment installer assigned to an area in Midwest U.S.A. My area consisted of Upper Michigan, Wisconsin, Eastern 1/2 of Minnesota, Northern 1/2 of Illinois, Eastern Iowa and North East Missouri.

Fairchild Graphic leased a bare bones Chevrolet vehicle, low quality heater and no radio. You had a large selection of parts you carried with you.

The Midwest Area Field Office was located in downtown Chicago. They created a weekly route schedule, however, it was changed any number of times within the week.

The following pictures and words on these pages might sound strange and not make a lot of sense to most readers, however I will attempt to explain in simple terms about  what is going on with type composition in the 1960’s era of typesetting.

 

The pocket rule (better known as the code rule) that many
TTS perforator operators and monitors (machine tenders)
carry on their person. Line gauges & code rules – a must!


Presumably most of our readers already are acquainted with Teletypesetter and the increasingly important role it is assuming in lhe graphic arts industry. For those who are not, as well as for the many already in the industry who are currently seeking to expand their capabilities, we offer the following by way of introduction.

The Teletypesetter method of producing type is a semi-automatic procedure for obtaining maximum results from linecasting machine operation. It begins with the preparation of tape on a typewriter-like machine known as the TELETYPESETTER PERFORATOR and ends with the utilization of this tape in a TELETYPES ETTER OPERATING UNIT installed on an Intertype or Linotype linecasting machine - where it operates the linecasting machine automatically at its geared output level, turning out lines of type ready for use.

This modern composing room procedure has opened up a new and rapidly expanding field for qualified touch system operators. In the publishing plant the Perforator Operator has the "key" assignment of translating copy into the tape which will control the entire sequence of operations performed by the linecasting machine in turning out the finished lines of type. It is a challenging task which demands both speed and "know-how" - the ability to produce tape that does not require "reruns" or manual corrections on the linecasting machine.

How a Linecasting Machine Operates

FOR MANY YEARS, the linecasting machine (Linotype or Intertype) has been a standard fixture in composing rooms, aiding immeasurably in speeding up the composition of type. Most readers are somewhat familiar with its manual operation-how the operator sitting at the keyboard depresses various keys to assemble matrices and spacebands, and th us forms the mold from which a finished line of type is cast.

In the Teletypesetter process, none of the functions of the linecasting machine are omitted, and no new functions are added.

The improvement in machine output is obtained solely by eliminating the peaks and valleys of stop-and -go manual operation and substituting the steady, continuous, top level production obtainable through automatic operation. Thus it is essential that we begin our training with a description of how a linecasting machine operates.

In larger typeshop operations like newspapers and commercial shops such as Blackdot in North East Illinois, R. R. Donnely, On the Lake Front, Chicago, Ill., Wisconsin Cuneo Press, North Side of Milwaukee , Wi. it was the norm for one machine tender (monitor) to be responsible for the continuous running 4 machines. This consisted to taking cast slugs from the machine and pass them over to the proof press operator, inserting new perforated tape onto the Teletype Operating Unit when needed and attending to assembling of matrices when required.

Larger shops had a call board (triangular box hanging in the middle of the composing machine area that had 3 panels of numbers representing each machine) that would light the number of the machine and ring a bell or gong when the monitor would press the call button located on each machine. This call button was used not only by TTS monitors but also was used by manual operators (one person/one machine) for any machine malfunction or problem such as stuck lines of type (in mold) or distributor (roof) stops. On duty machinists would respond to all calls and also hang new pigs of metal on the pig feeder.

Linecasting Machine Keyboard



A LlNECASTING MACHINE KEYBOARD contains 90 keys, arranged in six rows of 15 keys each, plus a spaceband lever. Figure illustrates a standard fraction linecasting machine keyboard arrangement. Keybuttons are generally arranged in three colors: lower case characters, black; punctuation marks, figures, and special characters, blue; and the capitals, white. The release of a matrix from the linecasting machine magazine is the final result of a sequence of operations begun with the touch of a keybutton.

 

This is a standard layout supplied for Teletypesetter operation where fractions are required.

Matrix – Almost like a Jello Mold – Hundreds of them
Moving Within the Mah-chine!

A MATRIX is a small piece of brass with a letter of the alphabet, figure or some other character recessed into its edge. The matrix is used as a mold to reproduce a corresponding character in type. The linecasting machine magazine contains 90 channels of matrices, each channel having a capacity for 21 identical matrices. When a line of matrices has served for casting the line of type, each matrix is automatically distributed to its proper channel.

Multiplying the 90 channels in the magazine X’s 21 =’s 1,890 matrices could fit in a magazine. Now you might have requirements for 21 loser case “e”s but why have 21 capital “E”s? The vowels “a”, “e”, “i”, “o”, “u” and “y” channels contained more matrices than most other channels in the magazine. For sure you don’t need more than 10 “x”s or “z”s.

“Double e” Attachment Arrives!

And for you purists, I’m not forgetting the “Zero” channel – better known as the “double e” channel.

So WHAT’S a double “e” channel. This channel was mainly used when TTS units were adapted to higher output (lpm)  Linotype Comet and Intertype Monarch linecasting machines. Each time the line delivery moved from home position to the left to deliver a line of matrices a selector lever was camed (Comet) left or right. (Not sure on about how Monarch did this) This caused a “0” or “1” reed to select lower case “e”s from channel # “0” or # “1” when assembling the next line of type.

Just think what happened the first time you set a story about history for the song using this word:
“eeeee i eeeee i eeeee iO”. A song “Ol’ McDonald Had A Farm” used
eeee-i -eeee-io!.
(Don’t laugh! Polka bands in North East Wisconsin – Frankie Yankovic & Cousin Fuzzy – played tunes with that word) That line used 15 or the 21 lower case “e”s. Only 6 “e”s left in the magazine. Had to wait for the line to cast and “e”s get returned to the distributor bar and fall into #“1” channel. With the “double e” selector working I could continue setting the next line, this time using “e”s from the “0” channel.

 

Spaceband (Wedge) – the justifying word space




THE SPACEBAND consists of a unit of two thin wedge-shaped pieces of metal used as spacers between words of a line. Upon completion of the line, the spacebands are automatically separated from the matrices and returned to the spaceband box. Each line of type must contain at least one spaceband when line justification is required
.

WEDGE
Two tapered steel pieces forced upward on stationary sleeve to create justified line of type. (sample below)



STOP PIN
Prevents SLEEVE from sliding off bottom of wedge.

Assembling a Line of Type (Manual Operation)



As THE MANUAL operator "keyboards" copy, matrices are released from the magazine. The matrices fall by gravity to a rapidly moving conveyor belt, which carries them into an assembling elevator, assembling the matrices into words.

In response to the operator's touch of the spaceband lever at the right time, spacebands drop between words. Visual judgment of justification is accomplished by the operator's knowledge of total expansion of the spacebands in the line compared to the amount of space left to fill the line. If the line fails to meet justification, the operator must add the required extra spacing to the line.

 

 

A= Magazine of matrices; B=Matrices dropping down the face plate for assembly;
C= Assembling Elevator; D= Spaceband box holding spacebands;
E= Spaceband chute.


Sending Assembled Line of Type to Casting Position


THE MATRICES AND SPACE BANDS which have been selected to form the line of type are elevated and transferred automatically to the casting mechanism where they are locked in place against the mold .

Just before the casting of the line , the wedge-shaped spacebands are forced upward to spread the line to the exact column width. This is known as justification.


Justifying a Line of Type

A slug (line of type) is formed by forcing molten lead into the mold, thereby filling the depressions of the letters in the matrices and at the same time forming the body of the slug.


(see lines of type on machine galley – below)

 

 


Ejecting a Slug (Line of Type) from the Mold

The metal in the mold cools and hardens almost instantaneously. The slug is then ejected, trimmed, and delivered to the galley, and the matrices and spacebands are redistributed to their storage channels.



Until recent years linecasting machines were operated manually by an operator sitting at the keyboard. Today they are operated automatically – at a speed and cadence impossible to match by manual operation – by a tape-controlled device known as the Teletypesetter Operating Unit, which attaches directly to the linecasting machine keyboard.
















Teletypesetter Operating Unit




THE TELETYPESETTER OPERATING UNIT is a self -contained unit that can be attached to all varieties of modern ninety -channel linecasting machines. Once a linecasting machine is so equipped, it may be converted instantly from automatic to manual operation — or vice versa — merely by turning the tape feed control lever on the Operating Unit.

 


Paper tape reel



It is the function of the Operating Unit (above) to "sense" the code combinations in the prepared tape and translate them into mechanical actions for automatic operation of the linecasting machine.


Since the Operating Unit can neither think nor act for itself but is actuated solely by the perforations appearing in the tape, it is obvious that the tape must incorporate provisions for all intermediate linecasting machine "functions," as well as select the characters and figures desired in the finished line of type. How all this is handled by the Perforator Operator is outlined in detail in Section II and Section III. Meanwhile, let's take a brief look at another important unit in the Teletypesetter process-The Teletypesetter Perforator.
